Template:RandomGalleryAnyPage
| Uses Lua: |
This template displays a random selection of images fetched exclusively from a **specified wiki page list**.
The underlying module has been updated to **only process lists** from the page specified in the first parameter; it no longer fetches images from categories.
Usage
{{RandomGalleryAnyPage|Page title (e.g., User:Example/Image List)|image height in px|number of images}}
Note: The page list must be a regular wiki page (e.g., in the User:, Project:, or main namespace) containing one image filename entry per line.
Important Update: Captions and Links
The module now supports full gallery entry syntax in your list page. Each line can contain the filename followed by a pipe and the caption, including wikitext (e.g., links):
File:Example.jpg|This is a caption with a [[Wikilink]].
Examples
{{RandomGalleryAnyPage|User:Suyash.dwivedi/My_Favorite_Images|50|12}}
{{RandomGalleryAnyPage|Project:Featured_List/Images_to_show|200|20}}
Debug Mode
To enable debug output:
{{RandomGalleryAnyPage|User:Example/List|200|12|debug=yes}}
Parameters
1— (Required) **Page list title** (must include namespace prefix like "User:")2— Image height in px (default: 200)3— Number of images (default: 12)4— Random seed (optional, default: current timestamp)debug— Set to "yes" or "1" to show debug information

Random Seed (`|4=` or `|seed=`)
The random seed controls the shuffling and selection order of the images. Using a fixed seed ensures that the gallery display is **stable** and remains the same across multiple page views, purges, or over time.
If no seed is provided, it defaults to `20260613214014`, which changes every second, resulting in a **highly unstable** (but freshly randomized) selection on almost every page load.
| Seed Value | Template Call Example | Effect on Gallery | Use Case |
|---|---|---|---|
| (Omitted) or `20260613214014` | {{RandomGalleryAnyPage|User:Example/List|200|12}} | Highly Unstable / Dynamic The images will change randomly on almost every page load or purge. | You want the freshest possible random selection every time a user visits the page. |
| `12345` (or any fixed number) | {{RandomGalleryAnyPage|User:Example/List|200|12|seed=12345}} | Completely Stable / Fixed The same set of random images will always be chosen from the list. | Useful for test cases, or when you want a fixed display that never changes. |
| `{{#expr:({{CURRENTD}}*10) + floor({{CURRENTHOUR}}/6) }}` | {{RandomGalleryAnyPage|User:Example/List|200|12|seed={{#expr:({{CURRENTD}}*10) + floor({{CURRENTHOUR}}/6) }} }} | 6-Hour Stability The selection is stable and remains the same for 6-hour blocks (00:00, 06:00, 12:00, 18:00 UTC). | Ideal for frequently rotating content that is consistent for short periods. |
| `6` | {{RandomGalleryAnyPage|User:Example/List|200|12|seed={{CURRENTDOW}}}} | Daily Stability The selection changes only once every day (at midnight UTC). | You want a gallery that remains consistent for all users throughout the day, but updates daily. |
| `202606` | {{RandomGalleryAnyPage|User:Example/List|200|12|seed={{CURRENTYEAR}}{{CURRENTMONTH}}}} | Monthly Stability The selection changes only once per calendar month. | Ideal for rotating "featured" lists or seasonal content that shouldn't change too often. |
| `Template:RandomGalleryAnyPage` (or any unique page title) | {{RandomGalleryAnyPage|User:Example/List|200|12|seed={{FULLPAGENAME}}}} | Page-Dependent Stability The selection is stable and unique to the page it is placed on. | Ensures that two different pages using the same list will have a different, but permanent, random gallery. |

Notes
- The module fetches image files only from the content of the specified wiki page.
- Image file entries in the list should be on separate lines.
- Images are randomly shuffled on each page load/purge.
- If the page is not found or is empty, an error will be displayed.
- Filenames can start with or without "File:" prefix - both formats work.
